This invention relates to paper receptacles and has particular reference to pa er boxes of the set up type and having closa le top or cover members.

The object of my present invention isto provide strong and durable set up boxes having integral cover members provided with Yside walls and which may be opened and closed a great many times without liability of spilling the contents or mutilating the members which serve to providecontinuity of the side walls of the top and bottom members of the boxes.

With the above stated object in view, the

invention consists in the boxes substantially as hereinafter described and claimed.

Of the accompanying drawings Figure 1 is a perspective view of one of the boxes in open condition.

Figure 2 represents a section on line 2-2 of Figure 1.

The'above-mentioned views are sufficient to illustrate the present invention, in view of the fact that the said present invention is an improvement on that illustrated and described in Letters Patent- No. 1,021,87 1 issued to me April 2, 1912, to which reference may be had for some of the details of structure. For convenience of comparison, most of the reference characters employed herein are the same as in said atent.

The chiefdi erences between the present structure and that of the patent referred to are that the present box is of the permanently set up ty e and all of the side walls are of double thlckness, while the box of the patent is of ythe type that is collapsible to flat folded condition and has side walls of but single thickness.

Although boxes having double-thick side walls are well known, there is a special cooperation in my improved box, between the double-thick side walls and thel `members which serve as continuing or connecting side walls between the double-thick walls of the bottom and top members, as will be explained hereinafter.

Referring to the accompanying'drawmgs, the bottom of the box is illustrated Vat'20,. to 500 which the top section 21 is connected bythe section 22. Integral withthe section 20 are the two permanently upright side walls comprising outer sections 23 and inner sections 23 folded over inside and lued, thereby providing substantially .sti wall members. The top or cover section 21 similarly has double-thick and glued side walls com rising outer sections 24 and in-folded and g ued sections 24. Preferably the end walls 14 and 15 are also of double thickness, the side walls 60- being notched as' at -16.

Integral with and connecting the outer side wall sections 23, 24, are intermediate side wall sections of the box material creased on com verging diagonal lines 25, 26, and slitted as at 66 27 to form triangular tongue flaps 28. These intermediate and connecting side wall sections just described are creased and slitted substantially the same as the similarly lettered parts of the box illustrated in the patent 70 referred to; and when the box is alternately opened and closed, the said creased and slitted side wall connections alternately stiaighten out and collapse or overfold as in said patent.

In said patent however, the side walls of the bottom and top members of the box were of single thickness, and necessarily7 so to enable the box to be collapsed to dat condition. Bein of single thickness, and also creased to enab e them to be folded to flat condition, they were insuiciently stiff to provide a box for practical and repeated use. Frequently, and especially after a few openings and closings duc to occasional dispensing of ortions of. the contents, the creases 25, 26, ailed to 35 function properly, and the edges where the slits 27 were made, became' mutilated and liable to catch together. This was due to the fact Athat the side walls lacked suicient rigidity to remain in proper condition so that 99 Vwhen closing the box the side walls of thelid member 21 would always swing over and pa down over the outer surfaces of the side walls ofthe bottom member \20. And sometimes the contents of the box would have a tend- 96, ency to press the sidewalls" out, 'and a person handling the lid member would sometimes Vpress its side walls in when closing the. box.

This prevented the proper iii-folding of the creasedandslitted intermediate wall connect- 10 ing sections which include the triangular tongue laps 28. It had a tendency to tear the tongues 28 down or away on the crease lines which hingedly supported them.

The preceding description of objections to the box of the prior patent is necessary to an understanding of the advantages possessed by the present structure in which the doublethick side walls of both the bottom and the cover or lid members not only increase the durability of the box as a Whole but also serve to so hold or maintain in proper positions the intermediate connecting creased Wall portions that-the box can be opened and closed many times without injury to said intermediate portions with their tongue flaps 28. So long as the latter are in good unmutilated condition, the box can be employed wide open to hold small articles on display, without risk of such articles escaping. This is because the said intermediate wall portions are, excepting for the short slits 27, continuous between the side walls of the two members of the box. This latter is true ofthe box of the patent referred to, but unless the connections between said side walls of the two box members remain in good condition of continuity they will not serve to retain small articles in the box. The present structure of double-thick side walls provides for ensuring proper folding operations of the creased and slittedwall connecting sections when the box is being closed, thereby maintaining the box in useful condition.

I do not limit myself to a. structure including the triangular tongue flaps 28 as the same may be omitted.

The advantage obtained by the presence of the notches or recesses 16 in the edges of the side walls of the cover member is that when the cover member is closed down over the bottom member, there are small areas of the side walls of the bottom member always exposed or un-covered, which areas may be conveniently grasped between a finger and thumb of one hand to hold the bottom member steadily while the other hand is being used to raise the cover member. This enables the box to be opened without risk of spilling its contents because the receptacle member of the box can be lirmly held while the cover member is being raised. This feature of my invention enables the boxes to' be made of such relative proportions that the cover member fits the bottom member very closely. Such close fit, if there were no notches present, such as at 16, would render the act of opening the box liable to cause a spilling of the conf tents when the cover member is lifted.

Having now described my invention, T claim:

A paper box comprising a bottom and lid and an intermediate section integral therewith, said bottom and lid having integral In testimony whereof AI have alixed my signature.
